Sample Printed Circuit Pattern (Cu-foiled area)

IC Usage Notes

(1) It is recommended to connect a surge absorbing capacitor across input pins 1, 2 and GND and across input pins 19, 20 and

GND.

(2) The base of a PNP transistor is connected to input pins 1, 2 and 19, 20. If an electrolytic capacitor is connected in series with

the input pins, connect input resistor RIN must not exceed 500 kΩ. (Reason: To minimize the variation in output DC voltage

at the time of input switching)

If a resistor of more than 500 k

Ω is connected across input pin and GND, the noise (output) caused by amp 1 and amp 2 select is

liable to increase at the time of F/R switching.

Unit (resistance:

Ω, capacitance: F)
